Analyst · Sandler O'Neill
Thank you, Phil. Good afternoon, everyone. This is Matt Funke, CFO of Southern Missouri Bancorp. The purpose of this call is to review the information and data presented in our quarterly earnings release dated Monday, April 24, 2017, and to take your questions. We may make certain forward-looking statements during today's call, and we refer you to our cautionary statement regarding those forward-looking statements contained in the press release.
To start out, we want to review the preliminary results highlighted in the quarterly earnings release. The March quarter is the third quarter of our 2017 fiscal year. We earned $0.53 diluted in the March quarter. That's up $0.08 from the same quarter a year ago, and it's down $0.03 from the $0.56 diluted that we earned in the linked December quarter. The current period includes some nonrecurring benefits, which we'll touch on below.
Asset growth slowed a bit during the March quarter, but loan growth was stronger. We had ended December with unusually high cash balance, and we showed asset growth of just $3.7 million, but loan growth was $16.3 million, which was just a little better than we did in the same quarter a year ago. Compared to March 31, 2016, gross loans were up $133 million. That's an increase of 12%. The investment portfolio was up slightly for the quarter and was up just over 4% for the last 12 months. Deposits were up more than $60 million in the March quarter and $150 million compared to last March.
In this quarter, we used traditional brokered CD funding to the tune of $115 million, and public unit deposits accounted for $19.3 million. Part of that $19.3 million was because a larger public unit depositor migrated from our [indiscernible] repurchase agreement balances into a deposit account. The breakdown of total deposit growth was about 1/3 CD growth and 2/3 nonmaturity deposit growth for the quarter.
Moving to the income statement. We try to update you each quarter on our fair value discount accretion on our loans and the smaller fair value premium amortization on time deposits that relates to our Peoples Bank acquisition, which is now approaching 3 years old. In the current quarter, that item decreased again to $216,000. You may remember that we had some higher accretion amounts in the June and September quarters of the 2016 calendar year. That resulted from the resolution of a particular purchased credit-impaired loan, then we saw a decline beginning in the December 2016 quarter.
In the year-ago quarter, March 2016, we recognized accretion of $322,000. And in the linked quarter, December 2016, discount accretion was $267,000. We do continue to expect the impact of discount accretion in total to move lower in the coming quarters, but we could see isolated increases due to continued resolution of individual impaired credit.
Net interest margin for the third quarter of the fiscal year was 3.64%. Of that, 6 basis points resulted from the fair value discount accretion we mentioned. In the year-ago period, margin was 3.72%, of which 10 basis points resulted from discount accretion. So on what we would look at as a core basis then, margin was down 4 basis points comparing this period to the year-ago period.
Our core asset yield was down 6 basis points, and our core cost of funds was down 3 basis points. Compared to the linked quarter, when our net interest margin was 3.70% and we had 8 basis points of discount accretion benefit, this would indicate our core margin is down 4 basis points. But that decline is primarily based on how we annualize our figures. We generally take a simple multiplication of 4 by our quarterly results. And if we adjusted that for the 90 days this quarter versus 92 days last quarter, in the December quarter, we'd actually expect our margin to have improved a few basis points on both a reported and a core basis.
The other side to that analysis is that we do have a few hundred million in scheduled-interest loans and most of our investment portfolio accruing scheduled interest, or 30 days interest each month, 30/360 basis. And those loans and those investments will perform better in a 90-day quarter versus a 92-day quarter.
Also, when you look at this current period compared to the year-ago period, the decline in our margin is somewhat attributable to the leap year in the prior period. So as we view our margin, we're in a fairly stable to slightly improving base, even though the reported results wouldn't necessarily show that.
Noninterest income as a percentage of average assets increased to 79 basis points as a percentage -- that's up 14 basis points compared to the same quarter a year ago. But we did note in the press release that we had almost $350,000 in nonrecurring benefits in the current quarter. That includes a BOLI benefit of just over $300,000 and then a smaller benefit from our sale of an interest in a low-income housing partnership. Outside of those items, noninterest income would have improved by 5 basis points compared to the year-ago period but it is a few basis points lower than where we've ran the last several quarters. However, for our March quarter, that's not too bad. We generally see a little more of a drop-off in NSF charges and secondary market loan sales this time of the year than what we did in the current period.
Noninterest expense was up compared both to the same quarter a year ago and compared to the linked quarter. We had $73,000 in expenses attributable to M&A this quarter. We had just a little more than that in the linked quarter. As a percentage of average assets, noninterest expense increased to 2.58%. If you back out those M&A items, our intangible amortization and seasonal swings in our provision for off-balance sheet credit exposure, we would calculate that our operating noninterest expense as a percent of average assets is up 4 basis points compared to the year-ago quarter and up 16 basis points compared to the linked quarter.
Compensation was the big driver in that increase over the linked quarter as we filled a few vacant positions. We added to our executive ranks. We processed our year-end compensation increases, and we absorbed an increase in our health insurance benefit. Occupancy remains stable from the linked quarter, but it is up year-over-year, as we've seen in the last several quarters.
Back to the balance sheet and asset quality. Nonperforming loans are now $3.1 million. That is 25 basis points on our total loans and down -- that's down from 45 basis points at December 31. The decrease of almost $2.5 million is attributable to the restoration to accrual status of several purchased credit-impaired loans, which have performed according to terms for a reasonable period and for which our collateral analysis indicates we're in a good position to be assured of the collection of all principal and interest due, net of any purchase accounting adjustments.
Nonperforming assets at March 31 were $6.5 million, declining in tandem with our NPLs, and they stand at our lowest level since before the Peoples acquisition, both in total dollars and as a percent of total assets, 44 basis points. We consider nonperforming assets to be our foreclosed and repossessed property, our nonaccrual loans and any loans 90 or more days past due.
Net charge-offs for the quarter were 6 basis points annualized. That's consistent with our year-to-date level so far for this fiscal year. Last fiscal year, by comparison, we were at 9 basis points for the full year.
The allowance as a percentage of our gross loans was 1.22% at March 31. That's unchanged from 12/31, been relatively stable over the previous 4 quarters. We provisioned $376,000 in the March quarter. That's down from the linked quarter and the year-ago period. As our analysis showed, we required less of an allowance due primarily to the reduction in NPLs.
We noted in our press release that the effective tax rate was 27%, down more than 4 percentage points from 31.7% the same period of last year, and it's a little below the 27.8% for our full fiscal year-to-date. The bank's formation at the beginning of this fiscal year of a real estate investment trust has benefited our effective tax rate, and the inclusion in the current period of the tax-advantaged noninterest income item related to bank-owned life insurance contributed to the lower rate in the current period.
That concludes my prepared remarks on the financials. And I'll introduce Greg Steffens, our CEO, to share his thoughts on our performance and update you on our strategic initiatives.
